俯冲

TheJunkers Ju 88 is considered to be the Luftwaffe's most versatileaircraft, being used in many varieties, each specialized in a role suchas fast bomber, dive bomber, torpedo bomber, night fighter, groundattack aircraft or reconnaissance plane.

容克斯Ju88被认为是纳粹空军最多用途的飞机，发展出多种诸如快速轰炸机、俯冲轰炸机、夜间战斗机、对地攻击机、侦察机等多种改型。

The low values of Nb/U (7~8) suggest that the basalts probably experienced the addition of some subduction-related materials and/or a certain degree of crust contamination.

较低的Nb/U比值(7~8)暗示该玄武质岩浆在形成过程中遭受了一定程度的大陆地壳混染或与俯冲过程有关的物质的加入。

Accompanying the Jungar plate subdueted dewnwards along the northwest edge of Siberian eraton, the volatile-rich felsie biotite diorite batholiths and a lot of fracture-controlled quartz diorite vein intruded the are-back basin, Au preferently distributed within the disseminated magmatic sulfide during granitoid melt crystallization

阶段Ⅰ。华力西晚期伴随着准噶尔板块向北部西伯利亚板块的强烈俯冲，在额尔齐斯弧后盆地形成偏中性富含挥发份深源黑云英闪侵入岩及大量明显受构造控制的石英闪长岩脉，Au在岩浆结晶-分异演化过程优先在花岗岩中呈浸染状分布的岩浆碱化物中相对富集

It is thus inferred that the central arogeny should have taken place between 2.55 and 2.50 Ga in North China craton.

华北东西陆块的俯冲碰撞应该发生在2.55~2.50 Ga期间。

Such cratons as Tarim and Yangtze are still of the thermal state for Precambrian lithosphere, while for North China craton, it is characteristiced by the thermal state for Mesozoic-Cenozoic lithosphere, due to reactivation associated with tectonic alternation.

中新生代期间西太平洋板块的俯冲和印度—欧亚大陆的碰撞等地球动力学过程分别控制了中国东、西部盆地的现代地温场特征。

The authors think that the magmas of the intermediate-acid volcanic rocks were derived from basaltic magmas of the lower crust and are mixed magmas produced by the increase of geothermal gradients due to diapiric injection of basaltic magmas and partial melting of intermediate-basic metamorphic igneous rocks in the lower crust,and that they resulted from a series of tectonomagmatic activities that took place when the closing of the Mongolian-Okhotsk sea trough and continent-continent collision caused crustal thickening and brought about the formation of the Hinggan-Mongolian orogenic belt in the process of oblique subduction of the Paleo-Pacific plate beneath the Siberian plate.

中文摘要：通过对大兴安岭北段晚侏罗世吉祥峰组中酸性火山岩的岩石地球化学研究，发现其中存在高Sr低Y型火山岩，即文献上所称的埃达克质岩，笔者认为中酸性火山岩的岩浆起源于下地壳玄武质岩浆，为玄武质岩浆底辟上侵引起地热梯度增加、下地壳中基性变质火成岩石部分熔融的之混合岩浆，是古太平洋板块向西伯利亚板块斜向俯冲过程中，蒙古鄂霍次克海槽封闭，陆壳碰撞使地壳加厚，形成兴蒙造山带时所引起的一系列构造岩浆活动。

This dissertation focus on rutiles, apatites epidotes and vein minerals from CCSD drill core and outcrops of Sulu-Dabie UHPM rocks, by detailed study of petrography, petro-chemistry, and mineral-chemistry, the implication of these minerals to UHPM and continental subduction-exhumation were discussed.

大别地表超高压变质岩中的这些副矿物和脉体矿物为主要研究对象，通过详细的岩相学、岩石化学、矿物化学等研究，对这些副矿物在超高压变质作用及大陆深俯冲—折返过程的指示意义进行了较为深入的探讨，在以下几个方面取得新的认识：1。

The mantle flux presents a fan-shape flow towards the Pacific oceanic region, and is possibly a field source at deep level of the Baikal rift system and East China.

它们的形成不仅受太平洋板块的俯冲和印度－欧亚大陆碰撞的制约和影响，而且位于中国西南部的地慢流发散中心，呈扇状向太平洋区流动，可能是它们在更深层次上的共同场源基础。

He climbed two thousand feet above the black sea, and without a moment for thought of failure and death, he brought his forewings tightly in to his body, left only the narrow swept daggers of his wingtips extended into the wind, and fell into a vertical dive.

http：//www.en8848.com.cn 他从漆黑的海面跃升两千英尺，根本没考虑到失败和死亡。他把前翅紧贴身体，只让翼梢上狭窄的，流线形的尖端迎着风，跟着就垂直俯冲。

The garnet-pyroxene granulites in the area are located at the suture of subduction-collision orogeney between the North China and Yangtze plaleo-continents in the Northern Dabie.

本区石榴辉石麻粒岩，位于大别山北部，华北-扬子板块俯冲-碰撞结合部，根据上述岩石形成的温压条件，表明是在板块碰撞过程产生挤压，地壳增厚，高压麻粒岩相条件下形成的。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
